LabVIEW based Power Analysis of Solar Tracking System and its Implementation in Real Time (Single Axis)

Abstract: The concern over the environment with respect to power and electricity, solar energy is used to orient various payloads towards the sun in order to the sun energy. Payload can be reflectors, photovoltaic cells, lenses or other optical devices. As the world population is increasing gradually the need for energy is increasing equally. Every day we depend on energy for the purpose of electricity, hot water and fuel for automobiles. Majority of this energy come from fossil fuels, such as coal, oil and natural gas. These are a non renewable energy source, which means that if we use them all up, we can never get more during our life time, so it is important that we use other energy sources, like renewable energy sources. These are energies that can be used again and again such as sunlight, water and wind. The main aim of this proposed system is to absorb maximum solar energy from the solar panel. Here the payload is photovoltaic cell. The solar tracker is the one which traces the sun’s movement continuously, such that maximum amount of sunlight falls on the solar panel which we have designed.
